Aaron Marino of alpha m. addresses if your muscles not symmetric and how to fix. The most important aspect of body building is symmetry. You don’t want huge biceps and skinny legs- you want to balance.
Aaron’s favorite symmetric body builders are Frank Zane and Flex Wheeler. The idea of symmetry is abstract since 99.99% are not symmetric. Look at your fingers and finger nails. One hand is bigger than the other, which goes for other body parts. The idea is that through consistent working out, your body will get as close to symmetric as possible. Using unequal weights to compensate is not a good idea. The lagging muscle group will catch-up as you work out with consistency. Symmetry requires working each body part equally and is attainable but not very likely.
